Instead, Johnson said he floated the gist of what would become Napolitano's report - that the British were gathering information on Trump and passing it to the United States - during an interview with RT, the news network funded by the Russian government.
A Senate committee on Thursday concluded that there were "no indications" Trump Tower was under surveillance by the USA government before or after the election.
Sir Malcolm told BBC radio: "That's just foolish and very risky stuff and President Trump better get a grip not only on his own press officer but on the kind of encouragement being given in the White House that makes a press officer make these stupid allegations in the first place".
When CNN asked him if the White House had apologised, Spicer said: "No, we were just passing on news reports".
Mr. [Andrew] Napolitano's unlikely leap into global politics can be explained by his friendship with Mr. Trump, whom he met with this year to discuss potential Supreme Court nominees.
Arsenal respond to claims over Dortmund boss Tuchel
The French manager's contract expires at the end of the season but he has been offered a new two-year deal. Troubled Arsenal have dropped to sixth in the Premier League.
President Trump on Friday refused to back away from allegations that he was wiretapped by British intelligence at the behest of the Obama administration, pointing the finger instead at a Fox News commentator. "He didn't use the NSA, he didn't use the Central Intelligence Agency, he didn't use the Federal Bureau of Investigation and he didn't use the Department of Justice - he used GCHQ", the former New Jersey judge had told the programme. "He used GCHQ - that's the initials for the British spying agency". So, simply by having two people saying to them president needs transcripts of conversations involving candidate Trump's conversations, involving President-elect Trump, he's able to get it and there's no American fingerprints on this.
The claim brought a rare public denial by GCHQ which described the claims as "nonsense" and "utterly ridiculous".
"It belies a complete lack of understanding of how the relationship works between the intel community agencies, it completely ignores the political reality of 'would the United Kingdom government agree to do that?' " Richard Ledgett said in an interview with the BBC.
During his presidential campaign, Mr Trump frequently accused the Chancellor of "ruining" Germany for allowing an influx of refugees and other migrants from Syria.
"No, no, it has not been raised", Spicer said. "I do believe he owes us that explanation". We're not casting judgment on that. Asked about the intelligence committee's report Mr Spicer said last night: "They are not findings".
